Given numbers are 838,651,754,336
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,651,754,336 is 1645342608.
Find LCM of 838,651,754,336 with Prime Factorization
| 2 | 838, 651, 754, 336 |
| 3 | 419, 651, 377, 168 |
| 7 | 419, 217, 377, 56 |
| 419, 31, 377, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 419 x 31 x 377 x 8 = 1645342608
Therefore, the lowest common multiple of 838,651,754,336 is 1645342608.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
838 x 651 x 754 x 336 = 138208779072
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
838 : 1, 2, 419, 838
651 : 1, 3, 7, 21, 31, 93, 217, 651
754 : 1, 2, 13, 26, 29, 58, 377, 754
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,651,754,336, is 1.
Now, the common factors can be found like this.
838:2x 419
651:3x 7x 31
754:2x 13x 29
336:2x 2x 2x 2x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 7 = 84
Therefore, the value for common factors is 84.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 138208779072/(1x84)
LCM = 138208779072/84
LCM = 1645342608
Thus, we can understand that the LCM of 838,651,754,336 is 1645342608.
